Stability of Serum Eye Drops After Storage of 6 Months

Abstract

The concentration of a spectrum of cytokines involved in corneal epithelial wound healing and the epitheliothrophic effect of serum are not significantly changed after a prolonged storage of 6 months at -20 °C. Hence, it seems justifiable to provide patients with appropriate freezer capacity with a 6-month supply of autologous serum eye drops. Albumin--which is known to be relevant for ocular surface health--could serve as a cost-effective parameter for stability controls.
